Title: Shinkichi Nozawa: Innovator in Methanol and Ammonia Production

Introduction

Shinkichi Nozawa is a notable inventor based in Funabashi, Japan. He has made significant contributions to the field of chemical engineering, particularly in the production of methanol and ammonia. With a total of 2 patents to his name, Nozawa's work has had a considerable impact on industrial processes.

Latest Patents

Nozawa's latest patents include an integrated process for the production of methanol and ammonia. This innovative process involves several steps, starting with the primary reforming of a gaseous hydrocarbon feed with steam to produce a methanol synthesis gas containing hydrogen and carbon monoxide. The process continues with the synthesis of methanol from this gas, followed by secondary reforming of the purge gas to create an ammonia synthesis gas. This gas undergoes high-temperature shift conversion to reduce its carbon monoxide content, and the resulting carbon monoxide-free ammonia synthesis gas is then subjected to ammonia synthesis.

Another significant patent is a process for manufacturing methanol, where the pressure during the preparation of the synthesis gas is equal to that in the methanol synthesis step. This method maintains operational efficiency by recycling the methanol-free stream back to the reaction zone for methanol synthesis, despite the lower pressure in that step.
